I purchased a new Macbook Air just under 1 month ago and the enter/return key had something stuck below the dome which caused it to click and stick. Apple wanted to do a top case replacement on a laptop which was less than a month old rather than swap it out and felt this was unacceptable given that the parts could be refurbished and it is a complex procedure which may leave it in a worse state. The authorized reseller I purchased it from allowed me to return it. I receive a second Macbook Air a few days ago. This time the delete key rubs against the casing because the excess plastic from the molding process was not trimmed from the corner of the key. This causes additional noise, sticking, friction, etc. Should I take it to the Apple Store to see if they can just remove the excess plastic or just return this one as well?
